I'm looking at this from a GPGME perspective.  If I tell GnuPG to 
symmetrically encrypt a file, I'd like for GnuPG to tell me what 
algorithm was used so that I can tell the user (in case they let it 
default to the s2k cipher algorithm, which the average user probably 
doesn't know off hand).  Maybe there's no way to do it?

At any rate this probably won't matter if I can specify the cipher

A quick test will show that you are correct, but the documentation says 
that the default is Blowfish.
